《Welcome to the Villains' world》

"My proud, beautiful flower of evil..."

The young girl desperately tried to move only for the strings holding her form to move tighter, cutting through her skin. Growling in pain, (e/c) eyes could only watch her brother fight his way against the monster who had held her hostage. She couldn't even keep her conciousness awake.

She lost alot of blood. Injuries littered her whole body. She never felt so helpless as all she ever did was rely on her older brother who had suffered so much for her behalf.

She couldn't even remember that much about herself. Ever since that day, all what had retained in her mind was the memories she had of her family.

The family of her human self.

She couldn't remember who she was, before becoming a demon. Her brother, who she had nearly ate, fought so hard for her sake. The moment he protected her from the man who weild a sword, what was left of her sanity, returned.

Her last family member. She couldn't just stand there and watch him beg for her sake.

"You are truly the fairest one of all..."

That was how it all started. She did her best to protect him yet her body was still adjusting to the blood that was injected to her. She needed rest.

What ever the man had told him, her and her brother travelled far only to be attacked by a demon. The very being she had become. That time, she had no choice but to use her remaining strength to protect him.

Then two years passed.

"Humans are to be protected... and saved... You must never hurt them... They're family..."

She had been asleep the whole time, and by a gentle voice filled with so much warmth, these words was forever engraved in her mind. Then on the moment she woke up, there was a strange feeling as if, things changed.

"O magic mirror, thy wisdom I entreat...."

Instead of her brother, there was an elderly man with a tengu mask tending over her. Much to her suprise, he was nothing but kind despite her being a demon. He wordlessly gave her, her brother's journals that he had wrote for her in the span of two years.

As she read, her heart aches. Even if his words was written off as nicely as he could for her, she couldn't help but imagine all the hardship he had been through all for the sake to revert her back to her former self.

A distant memory came, of the eldest sibling working so hard to earn for the family. She clenched her fists.

He became a demon slayer for her. To avenge their family.

"(Y/n)...."

His scent filled her nostrils. His blood. He is injured. Fighting to stay awake, she let out a growl, resisting the strings that restricted her movements. She can hear his shouts. She has to help him.

"(Y/n), please......"

Two gentle hands yet lack of warmth held both of her cheeks. Even so, she could sense the urgency on the owner's familiar voice. The hands different from the calloused ones her brother has.

"....Wake up...(Y/n)..."

That's right. (Y/n) is her name. She remember now. How could she forget her own name.

"Wake up, (Y/n)... please..."

She is trying too, but her body wouldn't allow it. She had lost a lot of blood and she doesn't have that much stamina anymore.

"Please, (Y/n).... Wake up... Save your brother.."

Her hand twitched. She could finally feel her conciousness returning. As soon as she did, the gentle voice began growing distance.

"You can do it now... (Y/n)... Do your best... Please, (Y/n)... Otherwise, your brother will die."

'Don't go...please...' She thought, now finally aware of her surroundings. The voice finally fades away, then she hears her brother's shouts becoming stronger. Then scent of his blood. Her eyes snapped open. 'Tanjiro-niisan!'

That's right. They are in the middle of a battle. If Tanjiro dies now, she'll be all alone. He is her last family.

"Reveal unto me the visage I seek..."

The blood on the strings started to light up. Her blood that was spilled. Reaching out her open palm, ignoring the constant stings from her healing wounds, The demon girl known as (Y/n) growled. Eyes lit up with anger and determination. 'Demon Blood Art-'

Her hand glew as she snapped her hands into a tight fist. '-Exploding Blood!'

(F/c) colored flames traveled through the strings towards the demon that controls it. Giving a perfect opportunity for her older brother to strike the demon's neck.

Her blood that was splattered on his blade started to ignite, further increasing the chance to severe the demon's head.

Her vision became blurry after that. The last thing she heard was her brother's voice, warmth filled her heart with his words.

"The bond between (Y/n) and me, can't be severed by anyone!"

"You, whos image the Dark Mirror did beckon forth..."

(Y/n) found herself in a dark room with only a strange mirror providing light. Her previous wounds, now healed and she felt as if she had regained the strength she had already consumed in battle. But unable to sense a presence, She frantically looked around in search of her brother only to be meet with nothing. She was the only one there.

Tears formed at the corner of her eyes, just at the thought of him still battling the demon who tried to claim her as his own sister. As she was to throw a tantrum, a whisper called out to her. Her attention was brought back to the mirror.

With a curious hum, she slowly walked closer and was suprised that instead of her reflection, it was all but green flames. Before an image of a hand appeared, reaching slowly towards her.

"If your hearts bids it, take the hand of the one reflected in the mirror..."

Strangely enough, she couldn't help but get drawn as images of several different young men flashed before her eyes.

One was wearing a feudora, underneat the hat was his light gray hair. Strangely enough his surroundings seems to be like he was under the ocean.

The next one sat on a what seems to be a flying carpet through an endless sea of clouds under the moonlight.

A rather flawless hand slowly made its way to a window, though through the reflection on the glass was a beautiful blonde male who seems to be frowning.

Inside a cave, lay a man with lion ears as quietly stared at the moon infront of him.

The rapid sounds of fingers typing on a strange Technology, (Y/n) isn't familiar with. But what caught her attention was his flaming blue hair.

A young man clad in white and red uniform sat besides a window. He casually sips his tea before looking outside. The small crown on top of his head slightly glistened.

"In me... In them... In you..."

Feeling no malice what so ever, (Y/n) who was now infront of the mirror, slowly reach her hand out. Grabbing the hand.

Who then pulled her inside. As soon as she entered the realm inside the mirror, she started to loose conciousness as her world blacked out.

"We all have little time left..."
